RAIL-SECURING nnvrcn.

Application filed January 7, 1922. Serial No. 527,577.

To allwhomz't may concern:

Be it known that I, PERCY LESLEY. REED, a citizen of the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented new and useful Improvements in Rail-Securin Devices, of which the following is a speci cation. f V

This invention relates to rail securing devices and more particularly to tie plates for railroad rails and consists in a new form of plate designed especially for use and cooperation with various types of rail. anchors. It hasas an important obje'ctand ad'- vantage the'protection of the wooden ties from injury incident to the use of the rail anchoring devices. My invention further consists in an improved method of rolling the tie-plates of my improved type. designed to facilitate their economical production.

An important function of. my improved tie-plate is .to prevent the wear on the ver-' tical side surface and the upper surfaces of cross-ties occurring from the use of the many types of rail anchorin devices which in practice are anchored y engagement with the side surface of the ties. Practice has shown that this arrangement, while more or less effective in anchoring the rails, has introduced an objectionable factor of decided economical importance in the resulting objectionable and destructive action of therail anchoring devices upon the wooden ties as commonly used. As is well known the several types of rail anchors which have gone into commercial use have small or comparatively small areas of abutment engaging with the tie as a result of which damage to the tie'oc curs.- The initial damage to the ties resultingfrom such wear are three-fold in character: First, a tearing and crushing of the fibre of untreated ties with a similar action uponthe fibrezof treated ties beyond the depth of penetration of the'impregnatmg or protective compound,r-thereby nullifying-the benefits of such treatment second,

to tearandcrushthe fibreof' treated or untreated crossties upon the upper surface thereofwherethe abutment portion of. the acceptedtypes of rail: anchors-cuts into the surface-of theltie until it impinges, against the edge of, the present-type of tie-plate; third, whenthe-latter occurs thepressures of the creeping rail are transmittedito the tie-plate "tending; to. alter its position. and applying the thrust toth'e spikes securing the tie and the railto the compound structure which results in both loosening of the tie plate and further damage to the ties. T1118. nitial damage to the .tie establishes conditlons which hasten the progress of decay from which the more substantial damage and subsequent losses occur.. 3:

A valuable feature of my .present invention,- having for itspurpo'se the elimination of the objections, aforesaid, consists in the usewith arail anchoring device of a spec1al1ydes1gned form of tie-plate provided- I w th; adepending protective flange of substantial area positioned at the side: of the cross-tie and interposed between the abutment port1onofthe anchoring device, and

the. tie to protectthe latterfrom wear. The

arrangement thus, provided functions not .only to protect the tie,but further acts to oppose and reduce the travelling of the rail anchor and the railto which it is attached therebyincreasing the efliciency of the anchoring device.

The foregoing and other features and advantages of my invention will be more fully .understood by reference to the accompanying drawings wherein I have illustrated a 1 proved embodiments thereof and wherem like reference numerals are applied to the corresponding parts in the several views.

In the drawings:

Figs. 1,2 and GWherein a similar view illustrating-a furthere is illustratedithe'irailsecuring means 1 ofmyinvention having'incorporated there- .with myimproved tieplate designed for. use

with rail 'anchors inv itsreferred formal indicates the usual-.;cross-. t1e', 2-myz improved type oftie-platebearingithereon-provided I vided at least at one side thereof as here shown, with an integral depending flange 6 positioned to overlie the upper side surface of the usual wooden cross-tie 1 and formed of substantial depth and desirably extending the full width of the tie-plate as indicated. As best shown in Figure 1 the protective flange 6 provides a bearing portion for the engagement of the lug or abutment member 8 of the rail anchoring device a, which as illustrated, is of a well known form composed of the abutment member 8 and yoke 9.

The flange 6 as thus provided affords a contact or bearing surface positioned to be engaged by the abutment member of the rail anchor thereby to prevent the direct contact of the rail anchor member with the wooden tie and eliminating the wearing action which would result therefrom, which, as aforesaid, results in substantial damage to the ties in the present types of installation. This protective flange 6 may desirably be rolled in tegrally on the plates in the rolling operation which may advantageously be accomplished in the improved manner illustrated in Figure 5. As there shown, a composite or multiple bar is rolled of generally channelled form with the depending flanges at each side. This is severed centrallyand longitudinally and also divided transversely, as indicated by dotted lines, to produce the individual angle bar type of plates of my invention. The ribs 4 of this arrangement are formed by the rolls to extend transversely of the multiple bar which may be .successfully accomplished by reason of their being of relatively slight depth. It will of course be understood that my improved protective tie-plates may be otherwise produced, for instance by rolling in the usual manner and thereafter bending down or bulldozing the metal to form the depending flanges.

In further accordance with my invention, as shown in Figs. 1 and 5, I have designed my improved .plate to have incorporated therewith further improved features possessing valuable advantages both in respect to mechanical action and also from the standpoint of commercial production. As will be noted in longitudinal cross-section'the horizontal portion of the plate is of relatively greater thickness on the edge furthermost from the depending flange and progressively decreases in thickness upon a curved line from a point about one-third of the distance from the plain edge of the plate to a point of connection with the depending flange where the minimum thickness of the plate obtains. This improved arrangement provides for a reduced area of bearing contact with the rail base and formatively allows for the normal wave motion of the rail under the action of the rolling stock and also effects a reduction of the weight of metal employed with resulting economy. In the described arrangement, the presence of the depending flange affords additional strength by reason of its substantial reinforcement, with respect to the vertical plane, which allows of obtaining the aforesaid advantages without impairing the strength of the tieplate which may accordingly be of substantially uniform strength throughout its length.

As will be appreciated the features of my invention are susceptible of various modifications without departing from the scope of the invention as defined in the appended claims. As illustrative thereof I have shown in Figs. 3 and 4 suitable modified forms having at both the forward and rearward edges the depending protective flanges formed to coact with the rail anchors.

In the specimen design of Fig. 3 the tieplate is shown having the horizontal member thereof' of uniform cross-section throughout its length and provided at the forward and rearward edges with the integral protective flanges 6--6, space to receive between them the usual wooden tie 1. As shown, each of the protective flanges is engaged by the abutmentmember of a rail anchoring device applied to the rail so as to resist creeping action thereof in either direction.

The arrangement of Fig. 4 corresponds generally to that of Fig. 3 but wherein the horizontal bearing member of the plate in its longitudinal cross-section has its upper surface curved in contour with the result that the central portion of the plate is of maximum thickness and of progressively decreasing thickness forwardly and rearwardly therefrom.

I have thus produced an improved tieplate which in its combined use with rail anchoring devices will fully protect the ties thereby eliminating the important objectionable factor of the substantial indirect losses incident to the use of rail anchors as heretofore used. In the latter connection "it will readily be appreciated that the prevention of physical wear of wooden crossties is of growing economical importance by reason of the yearly increasing cost of the ties by reason. of the serious depletion of the source of supply. y improved arrangement is further advantageous in that the protective flange operates to prevent movement of the tie-plate relative to the tie and in consequence eliminates the cutting of the tie by movement of the plate and of the spikes from which further substantial losses occur. The opposition to movement of -the plate offered by the flange will also to a large degree operate to prevent loosening of the holding spikes.

Having described my invention I claim:

1. A base or tie-plate provided with a rail bearing member adapted to be secured to a tie and formed With a depending protective flange positioned to overlie the upper portion of the side surface of the tie, the horizontal bearing portion of said tieplate in its longitudinal section being of progressively decreasing cross-sectional area toward the flange side thereof, substantially as described.

2. A base or tie-plate formed with a hori- Zontal rail bearing member and provided upon one side edge thereof with a depending protective flange positioned to overlie the upper portion of the side surface of the tie, said flange extending transversely the full width ofthe tie-plate and the horizontal member of said plate for its full Width having its upper surface of curved contour providing a progressively decreasing longitudinal cross-sectional area toward the flange edge of the plate, substantially as described.

3. A rolled tie-plate provided with a horizontal rail bearing member provided at one edge with a depending protective flange adapted to overlie the upper portion ing formed by the rolling of a multiple plate section of channelled form and dividing said section centrally and longitudinally and transversely into the individual plate lengths and said plate being rolled to form the rail bearing member of reduced thickness at the flange side thereof, substantially as described.

5. A base or tie-plate comprising a rail bearing member adapted to be secured to a tie and a depending protective flange p0- sitioned to overlie the upper portion of the side surface of the tie, the bearing member of said tie-plate in a longitudinal plane being of progressively decreasing cross-sectional area and depth toward the flange side thereof from a point in close proximity to the edge thereof opposite the flange, substantially as described.

In testimony whereof I have signed my name to this specification.
